Let's divide 425440 by 71
The aim is to understand the frequency of 71 in 425440.

Let's proceed to step 1:
If we divide 4 by 71, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 71

On to step 2:
71 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 71

Step 3:
The number 71 fits into 425 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 355 from 425, we get 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 71

Advancing to step 4:
71 can be fit into 704 9 times, resulting in a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 59.0
The remainder is 65 after subtracting 639 from 704.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 71

Let's proceed to step 5:
If we divide 654 by 71, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 599.0
If we subtract 639 from 654, we get 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 71

Moving on to step 6:
The number 71 fits into 150 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 5992.0
If we subtract 142 from 150, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
71 goes into 80 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 5992.1
If we take 71 away from 80, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
90 divided by 71 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 5992.11
Subtracting 71 from 90 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 5992.11 and a remainder of 0.019.
